Title: Method and apparatus for the production of gas suitable for chemical syntheses
IPC: C10J3/04
Filed: 1947-02-18
Abstract: 633,718. Gas producers. SOC. ANON. FORNI ED IMPIANTI INDUSTRIALI INGG. DE BARTOLOMEIS. Feb. 18, 1947, No. 4698. Convention date, June 10, 1943. [Class 55 (i)] Gas suitable for chemical syntheses is obtained from high volatile coals, lignite, &c. in a pair of alternately operated producers A, B, by injection of steam and oxygen or steam and an airoxygen mixture to gasify the fuel in one producer and the passage of the gas including distillates through a layer of incandescent coal in the other to effect cracking and hydrogenation of the tar and hydrocarbons. By means of cocks 15a, 15b in branches of a steam pipe 16 and cocks 18a, 18b in similar branches of a pipe 19 supplying oxygen or air and oxygen each producer can be blasted in turn and the final gases after descending the other chamber exhausted through a conduit 13. In ascending producer A the steam and oxygen are heated by the clinker zone; in the upper part fresh coal fed from hopper 9a is distilled and the mixed water gas and distillates pass through a conduit 5 into which a jet of oxygen is introduced through a pipe 6. Partial combustion occurring in the conduit and stabilized by a refractory plate 8 raises the gas temperature and effects distillation of coal charged into producer B ; increasing temperature down to the clinker level h<SP>1</SP> effects cracking and hydrogenation of the tar and hydrocarbons, the residual gases imparting heat to the clinker on their way to the outlet. In another arrangement a continuous supply of steam injects oxygen into a T-pipe with a branch to each producer.

Title: Bridge-t filter
IPC: H03H1/02
Filed: 1962-02-07
Abstract: 945,106. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 7, 1962 [Feb. 10, 1961], No. 4718/62. Heading H1K. A narrow band rejection filter comprises a PN junction having spaced ohmic contacts 10, 12 on the upper layer and a large ohmic contact 16 on the lower layer opposite the whole of the space between the first two electrodes and a further contact 20 on the lower layer spaced from the large contact. The upper layer, together with the PN junction forms a distributed resistance-capacitance circuit between. terminals 10, 12, the other electrode 16 and the lower layer forming the other terminal of the capacitance, which is connected via the portion D of the lower layer to the terminal 28, this portion forming the shunt resistance of the filter. The equivalent circuit is thus that shown in Fig. 1. The upper layer is characterized by a non-uniform doping impurity concentration decreasing rapidly from a high level at the surface 14 to substantially zero at the PN junction. This ensures that the series resistance between the electrodes 10, 12 remains substantially constant despite decrease in the effective thickness of the upper layer due to increasing reverse bias, the latter bias being applied to vary the capacitance of the PN junction The required doping distribution is effected by diffusion of the P-type impurity. Thus an N-type conductivity crystal of silicon may be diffused with P-type doping material such as indium, gallium, aluminium or boron. Adjustment of the series and shunt resistances may be effected by etching the surface 14 and the lower surface of the lower layer between the electrodes 16, 20. The semi-conductive material may be silicon, germanium, silicon carbide or stoichiometric compounds of Group III elements such as gallium, aluminium and indium with Group V elements such as arsenic, phosphorus and antimony. The ohmic contacts may comprise ohmic solders of e.g. molybdenum, tungsten, tantalum, or alloys of gold and silver.
